Question

我正在使用SpringMVC，我的jsp页面也可以，但是现在我尝试将我的应用程序与Thymeleaf集成。

thymeleaf-servlet.xml

TEXT

控制器：

INSERT INTO aes_test (username, encrypted) VALUES ('evan', AES_ENCRYPT('evan', '69552E16F55C3E88CF3CBC44EB5F71B24DD0CF5CB3A7C65EA97BC69224CF42F1'));

我的应用程序可以在下一个URL http://localhost:8080/MyApp/tl上正常使用，但不能与http://localhost:8080/MyApp/products一起使用

这是我的html文件：

test.html：

SELECT username, AES_DECRYPT(`encrypted`, '69552E16F55C3E88CF3CBC44EB5F71B24DD0CF5CB3A7C65EA97BC69224CF42F1') FROM aes_test WHERE AES_DECRYPT(`encrypted`, '69552E16F55C3E88CF3CBC44EB5F71B24DD0CF5CB3A7C65EA97BC69224CF42F1') = 'evan'

products.html：

当我尝试访问http://localhost:8080/MyApp/products时，出现下一个错误：

@Controller
public class ProductController {

    @Autowired
    private ProductService productService;

    @RequestMapping("/tl")
    public String tl() {
        return "test";
    }

    /* List all the products on the db */
    @RequestMapping(value = "/products", method = RequestMethod.GET)
    public ModelAndView getAll(Model model) {

        return new ModelAndView("products", "list", productService.list());
    }

我拥有Spring和Hibernate所需的所有依赖项（在与Thymeleaf集成之前，我的应用程序可以正常工作），我添加了这些依赖项以与Thymeleaf一起工作：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org" th:lang="${#locale.language}">
    <head>
        <meta charset="UTF-8" />
        <title th:text="#{title}">hello html5</title>
    </head>
    <body>
        <h1 th:text="#{hello}">hello world</h1>
        <p th:text="#{hola}">hola mundo</p>
    </body>
</html>

预先感谢您的帮助。

Answer 1

如果您的productService在方法上使用@Transactional，我想您忘记在xml中添加事务注释

<tx:annotation-driven />

请将以上元素添加到您的xml

无法从Thymeleaf获取事务同步的会话
